Titanium is a transition metal used as pins and plates to support badly broken bones. Titanium is extracted from an ore that contains the mineral titanium oxide. This oxide is converted into
titanium chloride. Titanium chloride is heated with sodium to form titanium metal. This reaction
takes place in an atmosphere of a noble gas, such as argon.
4Na(s) + TICLO - Ti(s) + 4NaCl(s)
Calculate the mass of titanium that can be extracted from 570 kg of titanium chloride.
Relative atomic masses: CI 35.5; Ti 48.
